Return a list of values (or a subsection of item data) extracted from the items in the
specified list. The last part of the route path (everything after
/data) will be used as a
JSON pointer
into each item's data.

If the JSON pointer is invalid or not found for one or more items in the
list, the API will respond with a
400 Bad Request status code.

If a If-None-Match header is included with the request and the
content of the header matches the hash of the requested item's data, the API will respond with a
304 Not Modified status code and the response body will be
empty. The request will not count towards the rate limit.

If no If-None-Match header is included or if the item has been
modified, a ETag header will be included in the response
containing a hash of the item's data so that it can be cached.

If a If-None-Match header is included with the request and the
content of the header matches the hash of the requested item's data, the API will respond with a
304 Not Modified status code and the response body will be
empty. The request will not count towards the rate limit.

If no If-None-Match header is included or if the item has been
modified, a ETag header will be included in the response
